GAME.

SPECIFICATION forming part of Letters Patent No. 652,477, dated June 26,1900.

' Application filed November 9,1899. ,Serial No. 786,360. (No model.)

To all whom it may concern.-

Be it known that I, BYRON 0. GRISWOLD, a citizen of the United States ofAmerica, residing and having post-office address at Vindsor, in thecounty of Hartford, State of Connecticut, have invented a certain newand useful Improvement in Instructive Games, of which the following is adescription, reference being had to the accompanying drawings, wherein-Figure 1 is a plan view. Fig. 2 is a view in central vertical section onthe plane denoted by the dotted line no so.

The object of the improvement is the production of a game which willserve at once for instruction and amusement, to which end theconstruction of the device is preferably substantially that describedbelow.

In the accompanying drawings the letter a designates the game-board,here shown as inscribed upon its face with a map of New England.

The letter denotes a tower, here shown as cylindrical in contour andlocated at about the center of the board. It has in its periphery one ormore ball-races, preferably two, here shown as spiral, with tangentialexits at their ends and of a size that will accommodate an ordinarymarble. The tower is supported in such manner upon the base as to becapable of adjustment .rotarily around its axis, whereby the j exit fromeach ball-race onto the board may be directed on any desired line overthe tower by simply setting the latter manually on its axial pivoteither before the ball starts or while it is running.

In the use of this device the object to be attained may be to cause theball to come to rest at a particular spot on the board, or, in thepresent instance, upon a particular division of the map, and this willnaturally in= struct the player as to the geography which the mapdelineates. The ball is placed in the upper end of one of the ball-racesand permitted to run down the same, and upon its exit therefrom it willbe delivered tangentially from the tower onto the board with a forcedepending upon the weight of the ball and the length of the race and ona line depending on how the tower has been set on its axis. If there area plurality of races, several balls can be played simultaneously or inquick succession, the tower remaining stationary or being adjustedrotarily meanwhile,

I claim asmy invention- In a game, the combination with a flat boardinscribed with a map upon its face; of a tower mounted upon a pivot atabout the center of the board and in such manner as to permit itsadjustment rotarily around its axis, and a plurality of spiralball-races in said tower whose exits deliver tangentially to its axialpivot and onto the surface of the board, substan- B.
